 Viscous Dampers

Viscous dampers are hydraulic devices that dissipate the kinetic energy of seismic events and cushion the impact between structures. They are versatile and can be designed to allow free movement as well as controlled damping of a structure to protect from wind load, thermal motion or seismic events.

Available in ratings up to 1,000 KIP, seismic dampers are well suited for large displacement and/or large load applications such as bridges, buildings, and large structures.
